Publication rate of abstracts presented at Japan Geriatrics Society Annual Meetings (2011-2012): a retrospective observational study

Publication Rate in English of Abstracts Presented at the Annual Meeting of the Japanese Society of Psychiatry and Neurology

BACKGROUND

Relatively low publication rates of abstracts presented at scientific meetings (i.e., 37.3%, 95% CI: 35.3-39.3) have been reported across various fields worldwide. However, no study has investigated the publication rate of abstracts presented at psychiatric meetings and factors associated with full publication in Japan. This study aimed to determine the proportion of conference abstracts in the psychiatric field that reach full publication in English and its associated factors in Japan.

METHODS

A retrospective study was conducted to determine the publication rate of abstracts presented at the annual meetings of the Japanese Society of Psychiatry and Neurology (JSPN) in 2013 and 2014, the largest psychiatric meeting in Japan, by searching for full-text publications in PubMed and Google Scholar. Furthermore, we examined factors associated with a successful full publication of the conference abstract.

RESULTS

Of the 737 abstracts evaluated, 132 (17.9%) were published in peer-reviewed journals; the publication rates for oral and poster presentations were 12.7% (46/363) and 23.0% (86/374), respectively. In multivariate logistic regression analyses, the following factors were significantly associated with successful publications: poster presentations (odds ratio [OR]: 1.67, 95% CI: 1.10-2.57), original studies (OR: 4.16, 95% CI: 2.44-7.47), and academic institutions (OR: 5.77, 95% CI: 3.44-10.19).

CONCLUSIONS

The publication rate in English of the conference abstracts presented at the JSPN annual meetings was relatively lower than those in previous studies. Further encouragement of the publication of the abstracts presented in psychiatric conferences in Japan would be helpful in disseminating scientific findings in the field of psychiatry.

Publication rates of abstracts presented at the 23rd (2013) and 24th (2014) National Turkish Orthopedics and Traumatology Congresses: We are not improving

OBJECTIVES

The aim of this study was to determine 1) the publication rates of podium and poster presentations from the 23rd (2013) and the 24th (2014) National Turkish Orthopedics and Traumatology Congresses in peer-reviewed journals and (2) compare these rates with publication rates from the 20th congress (2007) published previously. The secondary objective was to determine the time lag to publication and compare this data with the data from the 20th congress.

METHODS

All abstracts from the scientific programs of the 23rd (2013) and the 24th (2014) National Turkish Orthopedics and Traumatology Congresses were identified and computerized PubMed searches were conducted to determine whether an abstract had been followed by publication of a full-text article in peer-reviewed journals. The time lag to publication was also noted.

RESULTS

Of the 993 presentation abstracts (302 podium and 691 poster presentations) from the 23rd congress and of the 940 presentation abstracts (310 podium and 630 poster presentations) from the 24th congress, 278 (28%) and 234 (24.9%) were followed by a full-text article in peer-reviewed journals indexed by PubMed, respectively. The rates of publication of the podium and poster presentations were 39.4% (119/302) and 23% (159/691), respectively from the 23rd and 37.7% (117/310) and 18.6% (117/630), respectively from the 24th congresses. The mean time to publication of the abstracts from the 23rd congress was 12.8 ± 18.8 (median: 13, range: -140 to 47) months and the mean time to publication of the abstracts from the 24th congress was 11.1 ± 14.42 (median: 11, range: -73 to 39) months. Fifty (50/278, 18%) abstracts from the 23rd congress (mean -11, range: [-32]-[-1], median -5 months) and 37 (37/234, 15.8%) abstracts from the 24th congress (mean -10.4, range: [-73]-[-1], median -4 months) were published as full-text articles prior to the presentation at the congress.

CONCLUSION

The vast majority of abstracts presented at 23rd (2013) and the 24th (2014) National Turkish Orthopedics and Traumatology Congresses were not followed by publication of a full-text article in peer-reviewed journals. The publication rates of the abstracts presented at these congresses did not improve when compared with the 20th (2007) congress.

Publication rate of abstracts presented at the American College of Physicians Japan Chapter Annual Meetings (2013-2014): A retrospective observational study

BACKGROUND

Few studies have evaluated the publication rate of abstracts presented at Japanese medical specialty meetings.

METHODS

A retrospective observational study was conducted to determine the publication rate of abstracts presented at the American College of Physicians Japan Chapter Annual Meetings (2013-2014). Publication rates were determined by searching the MEDLINE database for full-text articles.

RESULTS

Of the 116 abstracts evaluated, 14 (12.1% [95% CI 6.1%-18.1%]) were subsequently published in peer-reviewed journals indexed in the MEDLINE database.

CONCLUSION

Further studies to investigate the barriers to publication among Japanese investigators and additional efforts to improve this low publication rate are needed.

Full-text publication rate of abstracts presented at the Japan Primary Care Association Annual Meetings (2010-2012): a retrospective observational study

OBJECTIVE

To determine the publication rate of abstracts presented at the Japan Primary Care Association Annual Meetings and the factors associated with publication.

DESIGN

A retrospective observational study.

PARTICIPANTS

All abstracts presented at the Japan Primary Care Association Annual Meetings (2010-2012).

MAIN OUTCOME MEASURES

Publication rates were determined by searching the MEDLINE database for full-text articles published by September 2017. Data on presentation format (oral vs poster), affiliation of the first author, number of authors, number of involved institutions, journal of publication and publication date were abstracted.

RESULTS

Of the 1003 abstracts evaluated, 38 (3.8%, 95% CI 2.6% to 5.0%) were subsequently published in peer-reviewed journals indexed in the MEDLINE database. The median time to publication was 15.5 months (IQR, 9.3-29.3 months). More than 95% of published abstracts were published within 4 years. The publications appeared in 23 different journals (21 English-language journals and two Japanese-language journals). Based on univariate analysis using binary logistic regression, publication was more frequent for oral presentations (7.3%vs2.0% for poster presentations; OR 3.91,95% CI 1.98 to 7.75), and for first authors affiliated with university-associated institutions (6.4%vs2.4% for first authors affiliated with non-university-associated institutions; OR 2.75,95% CI 1.42 to 5.30). Based on multivariate analysis, oral presentation and first author affiliation with a university-associated institution were still the only independent predictive factors for publication (adjusted OR 3.50(95% CI 1.72 to 7.12) and adjusted OR 2.35(95% CI 1.19 to 4.63), respectively). Even among 151 abstracts presented orally by first authors affiliated with a university-associated institution, only 18 abstracts (11.9%) were subsequently published in peer-reviewed journals.

CONCLUSIONS

The publication rate of abstracts presented at the Japan Primary Care Association Annual Meetings was extremely low. Further studies are warranted to investigate the barriers to publication among investigators who participate in conferences where the publication rate is extremely low.
